"ll El SPECIFICATION forming part of Letters Patent No. T/@3,690, datedFebruary 28, 1905.

VTo r/,ZZ 1072/0717/ it Tit/ty concern:

Be it knownA that we, Een( (UsrLAv ERIK- soN and PER L. LINDs'rnr'M,citizens o'l' the United States, residing at Arlington, in the countyet' Hudson and State of New Jersey,

.have invented and produced a new and uselul improvement in CentrifugalCream-Separators; and we do hereby declare the :following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art te which it appertains to make and use thesame, reference being' had to the accompanying drawings, and to numeralsol. reference marked thereon, which form a part of this specification. y

The objects of this `invention are to secure increased efficiency in theseparation of cream trom whole milk; to reduce the cost et' constructingthe separator and to secure a more simple structure; to facilitate thecleansing of the machine after service; to break up the whole milk intothin lilm-like streams or'eurrents, whereby7 the cream-globules arebrought into Contact with the ereaming-surfaces ot' the liner, and toobtain other advantages and results, some of which may be referred tohereinafter in connection with the description oli' the working parts.

',lhe invention consists in the improved centrifugal separator and inthe arrangements and combinations of parts of the same, allsubstantially as will be liereinalter set lorth and linally elinbracedin the clauses ot' the claim.

Referring to the accon'ipanying drawings, in which like numerals ofreference indicate corresponding parts in each ot' the several ligures,Figure l is a central vertical section ol our improved device, taken atline w, Fig. F 2 is a section ot' the same, taken at line Fig. is asection oil the device, taken at line i ai, Fig. l. Fig. i is a detailsection taken at line y, showing a milk-supply tube and certain liningmembers or partitions around the same. Fig. 5 is a detail elevationshowing certain perfor-ations or slots in the inner members ol. theimproved liner. Fig. G is a detail view of the outer member ol the linerwhich may be employed in connection with our invention.

Application filed December 29, 1903. Serial No. 186,995.

ln said drawings, 10 indicates the bowl, which may be seated on a shaftll in any suitable manner common in the art. At the centra] verticalaxis el the bowl is arranged a \vlioleluilk tube 12, whichextendsdownward to a longitudinal plate or flange .13 near the bettelnet' the bowl, the said l'iange lying a little up from said bottom andheld by means of ribs 14 or in any other suitable manner. The said plateor `flange 13 is preferably perforated, as shown more clearly at 15 inFig. 3. Above said i'lange, within the interior chamber ol the bowl,are, arranged hollow perforated liner members or partitions .1G 17,which have the lorm el: truncated cones in side ele vation. The loweryconical partition liti has its lower larger end seated upon the saidllange or plate 13 near its periphery, the said larger end oi' theconical partition preferably being o i a diameter about equal to thediameter et said plate 13 and lying closely near to the interior walloi1 the chamber within the bowl. The conical partition 1G extends upwardlrom the plate 13 toa point about mid way between the opposite ends ofthe bowl. as indicated iii Fig. l,the smaller u pper end beingpreferably made cylindrical, as shown at '18, to lit telescrniically thesmaller lowcreml I9 ol an inverted upper col'licallnember IT. lhe upperconical partiu tion is thus arranged with its small end dowuward and itslarge upper end upward and in engagement with the inner walls o'lI thebowl near the top ol said bowl. There the parti* tion 17 engages theinterior walls ol the bowl, small lugs or projections 20aml `formed,which serve to hold the partition '17 away lrom said interior walls, sothat narrow blueanilk passages 21, Fig. 2, are formed between the saidconical partition and the interior walls. We perfor-ate the conicalpartitions to permit a tralismission oi ll uid from one side to tl ieother. We prefer to form the perforations 2?) in said conical partitionsas shown in Figs. .1 and 5, the perforations beingl in the form of slotswhich are disposed at various angles, so as to 'lorm thin eddies orcurrents within the body of the lluid, so that one current or eddy willbe ilorced into contact with the other as the body el. the milk llowsLunvard. Thus this contact of the eddies tends to cause the creamglobules or particles to contact one with another, whereby the saidparticles will be agglomerated or joined, and thus enlarged to becomemore perfectly and readily acted upon by centrifugal force. The upperedge of the conical partition is preferably rein forced interiorl y by astrengthening-rib 24. l/Vhile we prefer to employ outside of saidpartitions 16 17 another vertical liner25, we may dispense with the sameand employ the oppositely-fiaring vpartitions alone; but for thepurposes of this case we prefer a special form of partition, (shownparticularly in Figs. 1 and 6, the invention of one of the parties tothis application. In reassembling the parts we first insert within thebowl the flanged feeding-tube and afterward insert the lower conicalpartition 16 on its seat on the flange or plate 13. IVe then apply tothe top of the lower said partition the upper partition, the latterbeing thrust into telescopic relation, as shown in Fig. 1, after whichthe cover 26 is applied to the bowl in any usual manner. When theoutside cylindrical lining-partition 25 is employed, we prefer to insertthe same between the large ends of the conical partitions, as shown inFig. 1. The lower conical partition 16 being first .insel-ted, then thecylindrical partition 25 is placed with its larger end pressing down onthe Lipper edge of the cylinder, the latter being thus held in place.-To maintain proper balance, we prefer to provide the bowl with suitablelugs or projections 28, Fig. 3, which enter notches or correspondingrecesses in the partitions, by which said parts are held in the properrelation to maintain the desired balance, as will be understood. Theserecesses and lugs or projections may be arranged in any suitablerelation common in the art. The oppositely-disposed conical partitionsserve to break up the vertically-movable body of liquid twice in itsupward course, the liquid being cut into thin film-like streams oreddies and being forced through the conical partitions twice, once nearthe bottom of the bowl and again near the top of the bowl, whichconduces to a thorough separation of the cream from the blue milk.

In operation the bowl being rotated on its axial shaft 11 in anyordinary manner the new or whole milk is fed down through the tube 12 tothe bottom of the bowl, where it spreads out through the passage 29 tothe 11p-passages 15 neary the periphery of the bowl, where the milk isbrought into almost immediate contact with the inner wall of the lowerconical partition 16, on which some of its cream is deposited. In saidpartition are the variouslyinclined long and narrow slots 23, throughwhich the iiuid flows, depositing its cream ical partition and the creamthereof brought into positive contact with the outer surface and wallsof the narrow slots, as will be obvious. At the top of the bowl thecream passes out through a cream-exit (not shown) and the blue milkthrough a blue-milk exit 30 in any usual manner.
